C's announce Johnson signing

BOSTON -- The Boston Celtics formally announced the signing of Chris Johnson on Friday.

As expected, Johnson's deal is a multiyear pact that will include future nonguaranteed seasons, which should keep him with the team this summer with a chance to make next year's roster (or be utilized as a trade chip if the team fills up at his position).

Johnson's deal will pay him roughly $320,000 as a pro-rated portion of the $788,872 minimum salary for a player with one year's experience (for salary cap purposes, that number jumps up to $359,000, a small but important difference as the Celtics navigate the trade deadline with a goal of avoiding the luxury tax line).

The Celtics are now committed to approximately $70.94 million in luxury tax calculations this season, leaving them about $810,000 from the luxury tax line ($71.75) in advance of the Feb. 20 trade deadline. Boston still has one open roster spot.
