Two and a half weeks locked up?

He once faced a felony rap, but it’s beginning to look like Charlie Sheen may only spend a couple more weeks in jail.

Sheen, arrested on Christmas Day for allegedly threatening his wife at knifepoint, has cut a deal to plead no contest to third-degree assault and receive a 30-day sentence, according to celebrity website TMZ.

With time already served, he could spend just 17 more days behind bars.

Sheen, who recently signed up for two more seasons with CBS’ “Two and a Half Men,” is due back in court Monday.
