The 24-year-old Venezuelan was signed on loan from Torino in Italy before the 2017 season. The loan was made permanent after Martinez scored five goals in Atlanta United’s first three games last season.
If Martinez can’t play, manager Gerardo Martino could turn to Romario Williams, who scored his first MLS goal in last week’s 5-0 win against LAFC, or Jon Gallagher, who has scored three goals for Atlanta United 2. Hector Villalba also is an option, but he didn’t train Tuesday or Wednesday. Villalba sometimes filled in for Martinez last season when he missed a stretch of games after sustaining a thigh injury while playing with Venezuela. Martinez missed 14 games last season because of injuries or injury-related reasons.
Ezequiel Barco didn’t participate in training Wednesday because it was a scheduled day off for him. Tuesday was his first time training with the team after sustaining a quad injury Feb. 26 ahead of the season-opening game at Houston.
Defender Franco Escobar also didn’t train Tuesday. He sustained a concussion in the second half of the win against Vancouver on March 17 that has prevented him from participating.
