UPDATE: The Patriots announced that they re-signed Morris later Sunday afternoon.
Morris had been with the Patriots for four days in May, initially signing a contract that included $20,000 in guaranteed money, which is a significant total for an undrafted player. But the Patriots soon after waived him with a "failed physical" designation.
According to Harty, Morris had been treated for a blood clot in his leg following his release.
Morris projects to an off-the-line role with the Patriots, and his presence adds depth as fellow undrafted linebacker Cameron Gordon has been sidelined for the last few practices and fellow rookie Deontae Skinner remains on the active/non-football injury list. While Morris is a longshot to earn a roster spot, he could be a strong candidate for the practice squad.
