Sealver Siliga’s 21-day clock to return from short-term injured reserve officially started ticking on Nov. 28. And on Dec. 6, it stopped.

The New England Patriots activated the 6-foot-2, 325-pound defensive tackle to the 53-man roster on Saturday, in preparation for Sunday’s Week 14 game against the San Diego Chargers, according to the NFL transaction wire.

Field Yates of ESPN was first to report.

Siliga was originally placed on injured reserve with a designation to return on Sept. 27, following a Week 3 foot injury versus the Oakland Raiders. But with second-year wideout Aaron Dobson placed on injured reserve due to a hamstring injury earlier this week, there was a vacancy for the former Utah Ute, San Francisco 49er, Denver Bronco and Seattle Seahawk.

No. 96 comes back to an interior line now occupied by Vince Wifork and Alan Branch against the run, and Chris Jones and rookie first-round pick Dominique Easley against the pass. Over his short tenure in Foxborough, Siliga has been been able to help against both.

The 24-year-old started two of his three games in September, recording 10 tackles in the process. And after joining New England for the final leg of the 2013 season, the 2011 undrafted free agent worked his way up from the practice squad to notch 23 tackles, three sacks and a forced fumble over the final five games of the regular season.

If active versus San Diego, he’ll have a chance to add on to those numbers.
