Ulrey secures spot on US team at IAAF worlds

FAYETTEVILLE, Ark. (AP) - Arkansas runner Dorian Ulrey has secured a spot on the U.S. team for the IAAF world championships next month.

Ulrey's time of 3 minutes, 35.23 seconds in the 1,500 meters at a meet in Rome was good enough to meet the "A" standard for the world championships in Berlin. The time was more than 4 seconds faster than Ulrey's previous personal best. It's also the second-fastest time in school history.

Ulrey will be a senior at Arkansas next season.

Company: Cowboys' roof replaced for `aesthetics'

DALLAS (AP) - The builder of the Dallas Cowboys' indoor practice facility tells customers that team concerns about "aesthetics," not structural problems, led to the ill-fated fabric structure getting a new roof last year.

Nathan Stobbe (STOH'-bee) of Summit Structures LLC included the explanation in a letter sent to customers of the Allentown, Pa.-based company. The letter, which was obtained by The Associated Press, seeks to reassure customers that their buildings are safe.

The May 2 collapse of the Cowboys' 80,000-square-foot facility is the fifth Summit building known to have fallen in the last seven years. A member of the team's scouting department was paralyzed from the waist down and 11 other people were injured less severely.

A person with knowledge of the Cowboys' facility at the time of the roof repair says there were several troubling issues, none relating to appearance. The source, who is in the building industry, cites defects in the fabric that could have caused structural problems if not repaired.

Stobbe acknowledged that there were "small holes in the fabric" that could have caused "small leaks." But he says they posed no structural problems.
