Dallas Cowboys tight end Princeton Fant leaves practice early Monday after an apparent knee injury during the team’s on-field work in full pads. Multiple accounts describe the incident occurring during a team period when Fant receives a knee-on-knee collision while being blocked backward into running back Israel Abanikanda. Fant stays on the ground for several minutes and is later helped to the trainers’ tent. Reports say he is unable to put weight on the injured leg when he is assisted off the field, indicating a potential lower-body injury. The Cowboys’ practice session is in the context of training camp, with full pads scheduled as part of the team’s preparations. No confirmed diagnosis or timeline for recovery is provided in the available reports. The situation is treated as an injury during practice rather than a game appearance, and additional updates are expected as the team evaluates the extent of Fant’s knee problem.
