Crabtree has been on the adjacent practice field rehabbing with the rest of the injured players. He looks fit when running down the sidelines and partaking in simple workout drills. Harbaugh said his progress has been good.
Meanwhile, Harbaugh said several players on the Non-Football injury list and Physically unable to perform list are on track to start practicing again after Week 6.
"We're counting down the days and we're down to one week," Harbaugh said about the injured players. "There's quite a few guys from Tank Carradine, Quinton Dial, Mario Manningham and Eric Wright as all [of them] could be practicing next week."
Quinton Dial and Tank Carradine have been on the Non-Football Injury list as they're coming off a torn toe ligament and torn ACL, respectively. Both players are eligible to begin practicing after the conclusion of Week 6's games and there is a three week window to practice with the team before a move must be made on the injured reserve or the 53-man roster by Week 11.
Manningham is coming off a torn ACL he suffered from last December while Eric Wright was initially signed as a free agent last summer before being placed on the non-football injury list.
