The Los Angeles Chargers waived one of their backup quarterbacks prior to training camp.

According to the team’s official site, the Chargers waived quarterback Eli Jenkins. Jenkins was one of 15 undrafted free agents signed in April.

Jenkins, a Jacksonville State product, was a duel-threat quarterback who finished his four-year career with 7,652 passing yards, 3,796 rushing yards and 89 total touchdowns. The 6-foot-2, 210-pound Jenkins was cut a day after the Chargers acquired quarterback Cardale Jones from the Buffalo Bills.

The Chargers will now go into training camp with four quarterbacks: Philip Rivers, Kellen Clemens, Cardale Jones and Mike Bercovici. Clemens, Jones and Bercovici will battle it out for the spot behind Rivers.

Clemens has been the Chargers’ backup QB since 2014, but the 34-year-old veteran has some competition. Anthony Lynn, Buffalo’s former offensive coordinator and Los Angeles’ current head coach, is the one who likely pushed for the trade for Jones, a 2016 fourth-round pick and former national champion with the Ohio State Buckeyes. Jones is a big body (6-5 and 250 pounds) with a big arm. Meanwhile, Bercovici, a former undrafted free agent, will be in his second year with the Chargers.

It’ll be interesting to see if Los Angeles keeps three quarterbacks on the active roster come September, as ESPN’s Eric Williams noted that 2013 marked the last time the team kept three quarterbacks on the roster to start the season. Rivers hasn’t missed a game since he became the starter in 2006, but finding a future replacement for the veteran quarterback should be considered a priority.
