Two Bills players sent to hospital due to heat

Buffalo Bills tight end Chris Gragg and fullback Evan Rodriguez were sent to the hospital on Wednesday due to heat-related issues, reports ESPN's Mike Rodak. 

Rodak had previously said that the two were not participating in the Bills' training camp practice Wednesday morning due to cramps. He later reported that they were sent to the hospital. 

Rodriguez has been released, while Gragg remains hospitalized, according to Rodak.  

As ProFootballTalk points out, nearly 13 years ago Korey Stringer died from heatstroke suffered during the Minnesota Vikings training camp, raising questions and awareness about how the team handled his on-field collapse.
