Los Angeles Lakers All-Star Anthony Davis continues to make pain-free progress on his right foot and there's optimism for a return to the lineup as soon as late next week, sources told ESPN on Friday.

The Lakers start a five-game trip Jan. 28 in Boston.

Davis, who has been out with a foot stress injury since mid-December, has been ramping up his activity recently, and coach Darvin Ham said Thursday that Davis is "progressing really, really, really well."

Davis had been experiencing a career renaissance before the injury, averaging 27.4 points on a career-best 59.4% from the field, 12.1 rebounds, 2.6 assists, 2.1 blocks and 1.3 steals.

The Lakers are 20-25 on the season and two games out of 10th place in the West -- the final play-in spot.
