Athletic Club defender Yeray Álvarez is back running at the LaLiga outfit's training ground, and could be back in action in under a month.
Yeray had surgery in late December after being diagnosed with testicular cancer, with Athletic saying he was making "positive" progress in the wake of the operation.
In a statement last week, the Basque side also revealed that, as things stand, the 21-year-old centre-back "will not need any complementary treatment".
Could be in selection contention inside three weeks
Having completed exercise-bike work over the past couple of days, he did jogging on the pitches at Lezama on Thursday, first alongside Athletic physio Xabier Clemente and then with team-mate Óscar de Marcos, who is recovering from an injury.
Athletic expect Yeray to rejoin group training shortly, with the club not ruling out a return to match fitness within two to three weeks.
