The Los Angeles Chargers defensive tackle returned to the team Monday after serving a four-game suspension for violating the NFL's policy on performance-enhancing substances.Even though Liuget has served his suspension Cheap Derwin James Jersey , he said he still hasn't put it behind him."For my own sanity, just to get out there and play I think will be great for me," Liuget said. "It was definitely tough watching the guys out there and knowing that I could contribute but I'm happy to be back."Liuget took full responsibility for the suspension when it was announced in March, but he has sued his former personal trainer Ian Danney. Liuget claims in the lawsuit that it was Danney who injected him with a substance that Liuget thought was an over-the-counter anti-inflammatory medication. Instead, he tested positive because the substance is banned by the FDA and NFL.The lawsuit was filed in Los Angeles on Sept. 18. Peter Ginsberg, who is representing Liuget, said nothing imminent is developing with the case.Messages and emails left with Danney's office in Arizona were not returned. An attorney for Danney is not listed on the district court case docket."It was emotional. I have to be more careful of who I hire and trust," Liuget said. "I do love this game and to be messed up like that is hard."Liuget went to San Jose to work out during his suspension. He said he did an hour of on-field work daily Cheap Melvin Gordon Jersey , concentrating on getting quicker out of his stance off the line, hand placement and honing his pass-rushing skills.Liuget's return could not come at a more opportune time for the Chargers (2-2), whose pass rush has struggled. Defensive end Joey Bosa has not played the first four games due to a foot injury, which has allowed teams to double-team Melvin Ingram.The Chargers go into Sunday's game against Oakland with eight sacks, which is tied for 22nd in the league. They had 12 after the first four games last season. They are also 26th in quarterback hurries (19) and tied for 22nd in quarterback pressures (41), according to SportRadar.Coach Anthony Lynn said he expects Liuget to immediately return to the lineup as long as he is in playing shape."He's an established veteran. We know what he can do," Lynn said. "It's unfortunate that he got suspended, but we will throw him back in as soon as we can."Liuget said he is happy to be returning to a team that is at .500 at the quarter mark of the season. The Chargers lost their first four games last season before winning nine of their final 12 and missing the playoffs by one game. They have not been at .500 or better after four games since 2015."Knowing that one game cost us last year Cheap Philip Rivers Jersey , it is good knowing that we already have two in the books. We can't put our faith in someone else's hands," he said.Follow Joe Reedy at joereedy LOS ANGELES CHARGERS (9-7)New faces: C Mike Pouncey, TE Virgil Green, S Derwin James, LB Uchenna Nwosu, QB Geno Smith, PK Caleb Sturgis, PK Roberto Aguayo.Key losses: S Tre Boston Cheap Keenan Allen Jersey , TE Antonio Gates, DL Jeremiah Attaochu, TE Hunter Henry (injury), CB Jason Verrett (injury).Strengths: Ample talent in place to build on last season's finish of nine wins in 12 games. Philip Rivers back for 13th consecutive season as starter along with formidable receiver corps led by Pro Bowler Keenan Allen. Pouncey already giving boost to run game with Melvin Gordon. Defense largely unchanged, but restocked with draft picks including James, Nwosu. Edge rusher Melvin Ingram has been monster in preseason. Have one of NFL's easier schedules and have five-game winning streak at tiny StubHub Center, clearly unaffected by presence of opponents' fans.Weaknesses: Already lost starting TE Henry, former Pro Bowl CB Verrett to season-ending injury. Defense could be uneven Drew Kaser Jersey , possibly lacking depth with questionable quality at linebacker and interior line. Run defense still not impressive after struggling last season. Still waiting to identify new kicker after four guys took turns failing at position last year, likely costing playoff berth with early-season woes.Fantasy Players To Watch: WR Mike Williams. Last season's seventh overall pick made no impact after starting slowly due to injury. That could change in huge way this season. Tall, speedy receiver has been outstanding in practices and preseason games, presenting big target for Rivers. Williams could be huge bargain in many leagues.Vegas Says: Super Bowl 15-1. Over/under wins 9.5.Expectations: Bolts believe they've got Super Bowl contender after encouraging finish to last season. Season opener against Chiefs should establish early favorite in AFC West. Rivers poised for another strong season with no signs of slowing down. Continuity on roster and coaching staff should boost chances. Must survive six-week midseason stretch with only one home game and trip to London. If Chargers can avoid injury problems that popped up repeatedly for previous teams, future looks bright.
