Touchdown.
30-17.
The lead was back to 13 points.
The 49ers' offense, led by Anderson, took the field once again.
But everyone could see that he was not the same player he'd been in the third quarter. His release time had slowed from 1.7 seconds in the first quarter to 2.3 seconds, and his movements had become noticeably sluggish.
With every throw, his right shoulder visibly hitched, pausing for a moment before he could complete the motion.
The hitch was perfectly clear on the high-definition broadcast.
The 49ers' head coach stood on the sideline, having flipped through his playbook countless times.
His gaze shifted from Anderson, turning to look at the backup Quarterback who had started warming up on the bench.
He raised his hand, signaling for a timeout.
"Marcus, come on back," he said, bringing the radio to his lips.
Anderson stood on the field as his coach's voice crackled through the earpiece in his helmet.
He didn't respond.
