Smyth emphasized Porter didn't suffer a second seizure but was left back in Denver as a precaution. Porter returned to practice on a limited basis this week.
Porter, who was lifting weights with former Saints teammate Jeremy Shockey when Shockey had a seizure in May 2010, suffered his seizure in mid-August and was held out of a preseason game against Seattle that week. The cause of the seizure was undetermined and he returned to the field the following week.
Porter had a monster debut for Denver in the season opener, breaking up five passes, collecting eight solo tackles and returning an interception for a touchdown that sealed the Broncos' 31-19 win over Pittsburgh his NFL-leading third career game-sealing score since 2009. That performance earned him AFC Defensive Player of the Week honors.
He hadn't had any more symptoms until two weeks ago while preparing to leave for San Diego.
Around the league
Redskins • Receiver Pierre Garcon says he has a torn ligament on the bottom of his right foot and he's hoping to avoid surgery.
Garcon described the injury that's sidelined him for four of Washington's past six games as a "plantar plate tear" near his second toe. The plantar plate is a ligament that holds a toe in its joint. Garcon said Thursday that "surgery is an option" that probably would end his season, adding: "But we don't really want to think about that at all."
Titans • Michael Roos has started every single game for Tennessee since being drafted in the second round back in 2005, a streak now in peril of ending at 119 straight. On Monday the left tackle had his appendix removed. He played through discomfort in last week's 35-34 win at Buffalo. When Roos returned home, he couldn't sleep and finally headed to the hospital at 4 a.m. where he met a team doctor. Roos watched practice Wednesday and Thursday and is being checked daily by a doctor before the Titans (3-4) play the Colts (3-3) on Sunday.
Redskins • Linebacker London Fletcher was being evaluated by a neurologist for a possible head injury Thursday and missed practice for a second consecutive day, putting his 15-year consecutive-games streak in doubt. Coach Mike Shanahan said Fletcher was checked for about six hours by a doctor for a "balance issue." Shanahan listed the 37-year-old Fletcher as not practicing because of head and hamstring problems. Fletcher has appeared in 231 NFL games in a row since entering the league as an undrafted rookie with the St. Louis Rams in 1998.
