In a mere minute last Sunday, Minnesota United's Lawrence Olum went from seated substitute to second-half starter in the team's scoreless tie at Portland.
That's truly about all the notice he received that center-back Ike Opara was ill and done for the day, and Olum was needed on a moment's notice.
"That's why I'm here," he said.
That's why in March United signed the veteran defender, known to his teammates as "Lo'' because of his initials.
By doing so, it reunited Olum with a Minnesota franchise and coach Adrian Heath, as well. Now 35, he played for the USL's Minnesota Thunder in 2009 and played for Heath in that same league in Austin, Texas, and Orlando.
United, which signed him because of his experience, versatility and dependability, might need some spot help to reach the playoffs for the first time in three MLS seasons.
United can clinch a playoff spot if it defeats Sporting Kansas City on Wednesday at an Allianz Field, which has sold out all season. Heath said Tuesday that he expected Opara back in his starter's spot.
A victory also would move United back into second place in the Western Conference in its pursuit of at least one home playoff game.
