A rainy forecast forced Lucas Oil Midwest LateModel Racing Association to cancel the eighth annual MLRA Spring Nationals at Lucas Oil Speedway in Wheatland, Mo. The weekend — halted for the fourth consecutive year by weather or the pandemic — won't be rescheduled.

With the $5,000- and $10,000-to-win races at Wheatland scrapped, MLRA competitors are now scheduled to open the season with five consecutive nights of racing beginning Tuesday at I-80 Speedway in Greenwood, Neb. Visit mlraracing.com for full details.

Among other weekend special events affected by weather:

Cash Money: The Dirt Track Bank Cash Money Super Dirt Series rained out Friday at Humboldt (Kan.) Speedway and Saturday at Springfield (Mo.) Raceway; Springfield's race was made up Sunday.
