Jason Terry is apparently very close to becoming the newest member of the Boston Celtics, according to a tweet from Marc J. Spears of Yahoo! Sports, who reports that sources of Y! Sports have said that Terry and the Celtics are in the final stages of a contract agreement. Terry, a veteran free agent guard, was linked to the Celtics in free agency.

Celtics are in final discussions on terms of a multi-year deal with Mavericks free agent guard Jason Terry, sources tells Yahoo! Sports.

Terry, who was 34 last season, averaged 17.1 points in 63 games -- only one of which he started. A bench specialist, Terry would bring a lot to a team like the Celtics, in need of all the scoring help they can get.

Of course, Terry is a shooting guard. So is Ray Allen. What all does that mean?

First, the reported signing of Terry could mean the end of the Allen era in Boston. However, the signing of Terry doesn't necessarily signal the end of Allen's tenure with the Celtics, as the team could bring Ray Ray back thanks to bird rights and give Terry a mid-level exception deal. Celtics coach Doc Rivers has made it clear that he would like to sign both.

No terms have been released on the Terry signing, which will make the picture clearer.
