The USC product was suspended for the first four games of the regular season without pay for violating the league’s policy on performance-enhancing substances.
Drafted in the third round last year as the possible center of the future for the Chargers, Tuerk was a healthy scratch for all 16 games in 2016 coming off an ACL right knee injury that cut short his final season at USC.
Tuerk struggled with keeping his weight up in the past. Tuerk said he played at about 290 pound last season, but hoped to be around 300 pounds when the season started.
Tuerk was part of the competition for starting center at the beginning of training camp but Spencer Pulley, signed as an undrafted rookie out of Vanderbilt last year, won the job.
The Chargers also released defensive end Whitney Richardson from the team’s practice squad, so there’s a chance Tuerk could be added if he clears waivers.
