According to Sport.PL, Bonomo's trial has been ended after not impressing the coaching staff.
The coaching staff was not satisfied with his performance against Sleza and he has received a trial offer from English club Sheffield, so there was no reason to keep him because the prospects for engagement were small. "We expect to sign a striker with a much higher level of skill, " explained club president Andrew Dadello.
Bonomo played in the second half of a friendly against Sleza Wroclaw that Miedz Legnica won, 2-0.
The striker from UC Berkeley went "straight to England" for a trial with Sheffield (F.C.? United? Wednesday?).
The New York Red Bulls have yet to comment on Bonomo's absence from training camp in Florida.
