SURPRISE, Ariz. -- Baseball officials have made no decision on whether to ask for a ban on ephedra in the major leagues, commissioner Bud Selig said Saturday.

The toxicology report linking ephedra to the death of Baltimore Orioles pitcher Steve Bechler earlier this spring has been received by baseball officials, Selig said.

Since Bechler died, Selig has banned players with minor league contracts from taking ephedra, and the players' union has urged players not to use the substance.

"Some say the owners realize fans like to see home runs, so they wink when talk turns to supplements and steroids,'' Selig said. "That couldn't be farther from the truth. Those in positions of power have to be concerned. We all should be concerned.''

While at the Texas-Kansas City exhibition game, Selig also denied that owners were in collusion to temper big-money free agent signings in the offseason.

"There are all kinds of trauma out there, in all kinds of industries,'' Selig said. "The economy is in a significant downturn and we are a microcosm of the American economy. I don't know how anybody can say they didn't expect us to be impacted. I don't know what world they are living in.''
