New England Patriots' NFL preseason game against Green Bay Packers was suspended on Saturday when rookie cornerback Isaiah Bolden was stretchered off the field after being hit on the head.
Bolden was inadvertently struck by Patriots team-mate Calvin Munson while the latter tried to tackle Packers receiver Malik Heath.
Patriots said Bolden, a seventh-round draft pick from Jackson State University, had "feeling in all his extremities" but was hospitalised overnight for observation with an update on his condition expected on Sunday.
The teams agreed to end the game with 10:49 remaining in the fourth quarter and Patriots leading 21-17.
