The Browns can only accommodate roughly 5,000 fans at their facility, and Browns President Alec Scheiner tells The Associated Press the team will have fans sign up beforehand so "that we don't turn away 2,000 or 3,000 fans who just show up." Scheiner says the team will announce when capacity is reached, but fans can still come and wait to get in.
The team is still working out final details of the registration process. The Browns will not charge admission.
Scheiner said the Browns have begun looking into moving their camp to a college campus.
Manziel's arrival has created a buzz around the Browns, who selected the popular Heisman Trophy winner in the first round of the NFL draft.
