Key Raiders suffer setbacks

A promising day of practice turned into a frustrating one for the Oakland Raiders on Wednesday.

The team started practice with rookie tackle Menelik Watson and defensive tackle Pat Sims, free-agent pickup. But both players had to leave practice early. Watson told the Oakland Tribune he is dealing with a calf injury. He hopes to return next week. Both Watson and Sims had been out of practice since training camp began July 26.

This is definitely a setback. Both players were expected to play a lot this season. It is particularly troublesome for Watson. The second-round pick from Florida State has a limited football background. But he has immense ability and needs to get as much camp work as possible. If he misses an extend period again, he will likely not be a factor when the regular season starts Sept. 8.

Also, receiver Jacoby Ford left the field early Wednesday. He has been dealing with leg injuries since 2011.

Not all was bad for Oakland on Wednesday, though. Cornerbacks Mike Jenkins and Tracy Porter returned to practice as did rookie running back Latavius Murray.
