Patriots WR Wes Welker, who is coming off a torn left ACL suffered last December, was placed on the active/physically-unable-to-perform list by the team on Tuesday.

Welker can come off the list at any time, but once he practices in training camp, he’s ineligible from being added back to the PUP list.

It appears the Patriots are being cautious. There have been several reports that Welker is very far advanced in his rehabilitation after surgery in February and that he will be able to perform fully at some point soon.

The Patriots’ medical staff likely hasn’t cleared him 100 percent for full contact and will want Welker to ease his way into practices. The Patriots’ veterans are expected to report for camp on Wednesday.

The team also placed OLB Shawn Crable and DT Kade Weston, a rookie, on the active/PUP list. If any of the three players lands on the reserve/PUP list, he would be forced to miss at least the first six weeks of the regular season.
