The Wizards confirmed late Monday night that Beal began complaining about soreness in his lower right leg, where he had a stress injury to his fibula, the smaller of the two bones, that prematurely ended is rookie season in April.
He had an MRI and the results will be known Tuesday, before the Wizards play the Los Angeles Lakers at Verizon Center (CSN, 7 p.m. ET).
If Beal isn’t available, that could push Martell Webster back into the starting lineup, or coach Randy Wittman may opt for Garrett Temple.
