Kevin Garnett, who suffered a strained right calf against the Detroit Pistons on December 29, returned to the practice floor today, according to The Boston Globe:

Just a week after suffering a right calf strain, Kevin Garnett returned to the court today at the Celtics' practice facility in Waltham to take some jumpers. Garnett wore his customary practice uniform and tights covering his legs but there was no brace or protection for the calf.

That link to the Globe's page also has two photos of Garnett on the floor. 

Contracts of Wafer and West Guaranteed

Also, according to Jessica Camerato and Chris Forsberg via Twitter, the Celtics will guarantee the contracts of guards Delonte West and Von Wafer.
