The Chargers announced on Monday that guard Matt Slauson will miss the rest of the season with a biceps injury and they made a roster move on Tuesday to get a healthy body on the roster. The team has signed offensive lineman Michael Ola to the 53-man roster. He’ll take Slauson’s spot as the team has placed the veteran on injured reserve. It’s the second time that the well-traveled Ola has spent time with the Chargers.
