Well it looks like he's injured with a pec injury but should be back in a couple weeks.
Not sure he's a candidate to rush and sign with someone if he can't pass a physical. May not be the worst idea for the guy to get to 100% and wait until there is some more demand for his services once the season starts and injuries start to accumulate. That said, if someone wants to pay him a decent amount up front in the hopes that he can compete in a month, he might not want to turn that down either.
