The Seattle Seahawks re-signed veteran fullback Michael Robinson, who revealed Tuesday that he was hospitalized and seriously ill when he was listed with a mysterious virus during the preseason before he was released.
Robinson said he had a reaction to an anti-inflammatory drug he was taking at the time.
"I was taking the prescription drug Indocin," he said. "I was taking it the prescribed two times a day, but I was dehydrated and you can't take those medications when you're dehydrated.
"Then I got sick at the same time, and the doctors said it was a perfect storm. I felt like I was just getting the flu but found out my liver and kidneys almost failed. It was pretty bad. It took about 2½ weeks to get over it. It was bad, man. I didn't realize how bad it was until I was able to look back and reflect on it."
Robinson was hospitalized in Seattle after the Aug. 17 preseason game against Denver and lost more than 30 pounds.
"I got down to 212, but I'm back up to 245 now," he said. "After the Broncos game, I knew something was different. I went to the hospital two separate times. I shouldn't have left. I was readmitted two days later."
Robinson missed the last two preseason games and was released at the end of the preseason.
"I'm realistic," he said. "I knew I needed to play to keep my job. I knew what my salary was. This is a business."
Robinson passed a physical Monday before being added to the 53-man roster.
He was Seattle's starting fullback the previous three seasons and a special-teams captain.
The Seahawks decided to go with younger players at the position in Derrick Coleman and rookie Spencer Ware, partially because of Robinson's $2.5 million salary. But the team was able to re-sign Robinson for $840,000, the NFL minimum for a player with his experience.
Coleman suffered a hamstring injury in the game at Arizona on Thursday night, and Ware has been out with an ankle sprain. The Seahawks placed Ware on injured reserve Tuesday to make room for Robinson.
Robinson, a former Penn State quarterback, is viewed as an outstanding blocker, helping Marshawn Lynch rush for a career-best 1,590 yards last season. The 30-year-old Robinson also was one of the team leaders the past couple of years and someone many younger players leaned on for advice.
"It feels awesome to be back in the building and get back to work," Robinson said. "I watched all the games and talked to Marshawn every day. I feel great. I'm normal as far as blood results and stuff. All my energy is back, and my weight's back."
