In the first several days of training camp, Eagles fans haven't seen much from DeMarco Murray.

The rushing champion from last season missed practice for the second time this training camp due to an illness, the Eagles announced.

Murray missed the opening day of training camp on Sunday with dehydration issues, but still did participate in individual drills. Newcomer Ryan Mathews took most of the first team reps at Thursday's practice, with Darren Sproles picking up the rest of the slack. Murray should be back with the team shortly.

Another newcomer who missed practice on Thursday due to injury is a bit more worrisome. Inside linebacker Kiko Alonso suffered a concussion this week and is out until further notice, according to reports. Alonso will now have to go through the league's mandatory concussion protocol and show that he can return to the field. Alonso is another player who is recovering from an ACL tear last season when he was with Buffalo.

Safety Jerome Couplin also missed practice on Thursday.
