The record-setting passer does not have a contract with the team.
"Yes, he will participate in the minicamp," agent Chad Speck said in an e-mail.
The Browns would not confirm inviting Harrell to the minicamp, which runs from Friday through Sunday.
Harrell threw an NCAA-record 134 touchdown passes. More impressive was his completion percentage -- above 70 in two 5,000-yard seasons.
