Reports from earlier in the day mentioned that McCown had a thumb sprain and could be one or two weeks, but it appears as though this timeline was conservative.
Mike Glennon took over McCown Thursday night and completed 17-of-24 passes for 121 yards and a touchdown during their blowout loss to the Falcons.
McCown, 35, signed a two-year, $10 million contract that includes another $5 million is incentives. He has a base salary of $4.75 million for the 2014 season and another $5.25 million coming his way next year.
We’ll have more updates as the news is available.
