SQL Server 2008 :: Replace Tablename In Multiple Stored Procedures?

I'm trying to replace a table name in 250 stored procedures. I found this script below which does a good job but it also finds tables with similar names. How can I limit the replacement to the exact table name? If my original table name is MyTable001, I do not want to find MyTable001_ID.

-- set "Result to Text" mode by pressing Ctrl+T

SET NOCOUNT ON
DECLARE @sqlToRun VARCHAR(1000), @searchFor VARCHAR(100), @replaceWith VARCHAR(100)
-- text to search for
SET @searchFor = 'MyTable001'
-- text to replace with
SET @replaceWith = '[MyTable002]'

[code].....
