Marcus Smart has been out of the Celtics' lineup for the past four weeks after punching a glass picture frame in a Los Angeles hotel room.

Smart was rushed to the hospital with a shard of glass still sticking out of his right hand.

“They pulled a glass piece out of the palm of my hand about that size (between two and three inches),” he said as he estimated the length with his index finger and his thumb. “They said there were two tendons that ran along the pinkie area. The glass was sitting right in between them. They were like: ‘You should play the lotto because you missed your tendons.’ They don’t understand [how I missed them].

“I thank God for that every day. It could have been worse. I’m glad it’s not.”

Smith was cleared to practice on Wednesday.

“I was devastated,” Smart said of missing 11 games with the injury that he said required 20 stitches to close. “Just from the fact that I couldn’t do anything to go out there and help.

“I’m a competitor. It’s one thing to sit on the bench because of something that happened that you couldn’t control. It’s another when it’s something you can control. I felt like I let my team down.”
