The Bears on Friday signed veteran tackle T.J. Clemmings and waived undrafted rookie guard Tommy Doles.
Clemmings, 27, has appeared in 41 NFL games with 32 starts over four seasons with the Vikings (2015-16), Redskins (2017) and Raiders (2018).
Selected by Minnesota in the fourth round of the 2015 draft out of Pittsburgh, Clemmings started all 16 games as a rookie at right tackle. He was part of an offensive line that helped Adrian Peterson lead the NFL in rushing with 1,485 yards.
Clemmings played in 15 games with 14 starts at left tackle for the Vikings in 2016, taking over the job after veteran Matt Kalil was placed on injured reserve Sept. 21.
Clemmings was waived by Minnesota during final cuts in 2017 and has been placed on injured reserve each of the last two seasons—with the Redskins in 2017 after playing in six games with two starts and with the Raiders last year after appearing in four contests.
With the Bears, Clemmings likely will compete for the backup "swing" tackle position with Rashaad Coward and others behind starters Charles Leno Jr. and Bobby Massie. Last year the role was filled by Bradley Sowell, who was moved from tackle to tight end this offseason.
