This will cost Iupati the next eight weeks of the season, but he could be a candidate to return later on in the year.
Iupati, 39, is a former first-round pick of the 49ers back in 2010. He played out his rookie contract with the 49ers before signing a five-year, $40 million contract with $22.5 million guaranteed with the Cardinals back in 2015.
Iupati stands to make base salaries of $8 million and $7.75 million over the next two years.
In 2017, Iupati has appeared in one game.
Painter, 27, is a former sixth-round pick of the Broncos back in 2013. He lasted just over a year in Denver before he was waived and later signed to the Browns’ practice squad.
After a brief stint with the Giants, Painter signed on to the Dolphins practice squad midseason in 2015 and returned the team on a future’s deal. However, he was waived coming out of the preseason and later claimed off of waivers by the Redskins.
The Redskins re-signed Painter as an exclusive rights free agent this offseason but waived him as they trimmed their roster down to the 53-man limit.
In 2016, Painter was active for five games for the Redskins and played a total of 10 snaps, according to Pro Football Focus.
