San Francisco 49ers wide receiver Michael Crabtree was activated from the physically unable to perform list, the team announced Tuesday.
Crabtree was sidelined several months recovering from a torn Achilles. He was injured during a spring practice, and had surgery in May.
To make room for Crabtree on the roster, the 49ers waived quarterback McLeod Bethel-Thompson.
Crabtree (6-1, 214) was placed on the Reserve/PUP List on Aug. 27. He later returned to practice on Nov. 5.
Originally selected by the 49ers in the first round (10th overall) of the 2009 NFL Draft, Crabtree has played in 58 career games (56 starts). As a 49er, he has tallied 260 receptions for 3,345 yards and 21 touchdowns.
"Crabtree coming back next week. And hopefully get a few other guys back," coach Jim Harbaugh said after reviewing Monday's victory over the Washington Redskins.
Last week, there were indications Crabtree could be on the roster but not on the field on game day for at least a week or two.
The 49ers pulled back Crabtree's activity after his first week of practice, rather than risk a setback.
Once Crabtree practiced on Nov. 5, he started the clock on the 21-day window that ended Tuesday, when the 49ers had to activate him from the PUP list or shut him down for the season.
Quarterback Colin Kaepernick threw three touchdown passes Monday, but Crabtree was his top receiver in 2013. Crabtree caught 85 passes for 1,105 yards and nine touchdowns last season.
Bethel-Thompson (6-3, 230) was claimed off waivers from the Minnesota Vikings on Oct. 9, and has been inactive each of the 49ers last six games.
