Friends of Brett Greenwood have organized a campaign to have his supporters wear green today in honor of his 24th birthday.

And with any luck, the former Pleasant Valley High School and University of Iowa football player might even be able to see them doing so.

Greenwood is displaying normal organ functions, has been taken off a ventilator and no longer is receiving medication to put him in a coma, according to Ed Morrissey, his former high school coach. Greenwood has been in an induced coma at University Hospital in Iowa City since Friday, only a few hours after he collapsed while working out at PV’s football field.

“All the signs are very positive now,” Morrissey said Tuesday evening. “It would be great if he could wake up on his birthday.”

Meanwhile, Bettendorf resident Teresa Achenbaugh has organized a campaign to encourage everyone to wear green today in support of Greenwood and his family. Achenbaugh’s daughter, Whitney, graduated from PV with Greenwood and now works for University Hospital.

“I was talking to my daughter, and she said, ‘We’ve just got to do something,’” Teresa Achenbaugh said. “We need everyone to do this show our support and love for Brett.”

Greenwood’s former Iowa teammate and high school rival, Pat Angerer, wrote on Facebook that he intends to wear a green thong because Greenwood would want it that way.

Greenwood was a four-year starter at free safety for Iowa and a second-team All-Big Ten selection the past two years. He was cut by the Pittsburgh Steelers less than a week prior to his collapse last Friday.
