NFL commissioner Roger Goodell say the league will evaluate the merits of marijuana usage as a pain releiver.

However, no change is expected at this time.

"We'll continue to follow the medicine," Goodell said during his annual Super Bowl news conference. "Our experts right now are not indicating that we should change our policy in any way. We are not actively considering that at this point in time. But if it goes down the road sometime, that's something that we would never take off the table."

NFL Players Association executive director DeMaurice Smith said Thursday preliminary discussions have been held about medicinal marijuan.

The policy would have to be drafted into the collective bargaining agreement in order to become official.

Goodell said he likes the policy the way it's currently worded.

"I am randomly tested, and I'm happy to say that I am clean," Goodell said, drawing laughter.
