The former football star at Ole Miss was taken to Mease Dunedin Hospital, where a CT scan did not reveal any fractures. Alford has since been released from hospital and diagnosed with a concussion, according to the Blue Jays.
St. Lucie's Tomas Nido hit a fly ball to shallow centre with the bases loaded. The infield fly rule was called, but Urena, the Dunedin shortstop, collided with a charging Alford, allowing the winning run to score.
It's been a difficult season for Alford, who exited Dunedin's home opener with an injured knee and missed a majority of the season's first month. Toronto's third-round Draft pick in 2012 has hit .205 with an OPS of .540 and one home run in 32 games.
