Via Josh Looney, we have word that Kansas City Chiefs defensive end Tyson Jackson and offensive lineman Ryan O'Callaghan are out for this weekend's game against the Cleveland Browns.
Jackson injured his knee against the San Diego Chargers last week and O'Callaghan was seen walking gingerly into the locker room after Thursday's practice.
Tyson Jackson is expected to miss 1-2 games with the knee injury, while Ryan O'Callaghan's status is really unknown at this point. He injured his right groin, according to BobGretz.com.
We'll have more on this tomorrow morning.
